California Association of Sanitation Agencies is a statewide nonprofit trade association representing municipal wastewater agencies, regional sanitation districts, and related public entities in California. It serves as a collective voice for members in regulatory, legislative, technical, and public outreach arenas, interacting with agencies such as the California State Water Resources Control Board, United States Environmental Protection Agency, California Department of Water Resources, California Environmental Protection Agency, and regional bodies like the South Coast Air Quality Management District. CASA coordinates with national and international organizations including the Water Environment Federation, National Association of Clean Water Agencies, United Nations Environment Programme, and the World Health Organization on water quality and public health matters.

History

The association traces its roots to mid-20th century efforts by California sanitation districts and municipal wastewater utilities to address emerging issues in wastewater treatment, water reuse, and coastal protection. Early membership included agencies such as the Sanitation Districts of Los Angeles County, Metropolitan Water District of Southern California, and municipal utilities in cities like San Francisco, Los Angeles, and San Diego. CASA engaged with landmark regulatory developments under the Clean Water Act (1972), state-level initiatives from the California Coastal Commission, and planning efforts tied to the California State Water Project. Over decades the organization expanded its role to include climate resilience initiatives aligned with the California Global Warming Solutions Act of 2006 and infrastructure funding advocacy associated with measures like Proposition 218 and federal infrastructure bills debated in the United States Congress.

Organization and Membership

Membership comprises municipal wastewater agencies, regional sanitation districts, joint powers authorities, and associate members from engineering firms, laboratories, and industry associations. Large members historically include the Orange County Sanitation District, East Bay Municipal Utility District, City of Sacramento Department of Utilities, and Los Angeles County Sanitation Districts. CASA’s governance typically features an elected board of directors drawn from member agencies and committees that parallel those found in organizations such as the California Municipal Utilities Association and the Association of California Water Agencies. The association liaises with state institutions like the California Legislature, the Governor of California’s office, and federal bodies such as the United States Congress to represent collective positions.

Programs and Services

CASA provides programs in regulatory compliance support, regional coordination, and technical assistance similar to services offered by the National Association of Clean Water Agencies and the Water Environment Federation. Service areas include wastewater treatment optimization, recycled water program development, biosolids management, and marine outfall coordination with agencies like the California Coastal Commission and the National Oceanic and Atmospheric Administration. It offers model contract templates, emergency response coordination linked to agencies such as Federal Emergency Management Agency and California Governor's Office of Emergency Services, and group purchasing or joint procurement facilitation modeled on practices of the Joint Powers Authority framework.

Policy and Advocacy

CASA conducts advocacy at the state capitol in Sacramento, interacting with committees of the California State Assembly and the California State Senate, and engages with regulatory rulemaking at the California State Water Resources Control Board and the Air Resources Board. Policy priorities have included funding for infrastructure via ballot measures like Proposition 1 (2014), regulatory flexibility for recycled water under the California Water Code, nutrient management strategies influenced by the Delta Stewardship Council, and climate adaptation consistent with plans from the California Natural Resources Agency. CASA collaborates with allied organizations such as the Association of California Water Agencies, the League of California Cities, and environmental groups involved with the Sierra Club or the Natural Resources Defense Council on shared policy objectives or negotiated regulatory frameworks.

Research and Technical Guidance

The association produces technical white papers, model ordinances, and guidance documents on topics including advanced treatment technologies, nutrient offset programs, and microconstituent monitoring, drawing on research trends from institutions like the University of California, Davis, Stanford University, California State University, and federal research from the United States Geological Survey. CASA-supported studies have examined wastewater energy recovery, biosolids beneficial reuse consistent with guidance from the United States Department of Agriculture and the United States Environmental Protection Agency, and risk assessments informed by the Centers for Disease Control and Prevention. The association convenes expert panels and technical committees similar to those of the Water Research Foundation to synthesize peer-reviewed evidence for member implementation.

Education and Training

CASA offers workshops, webinars, and conferences providing continuing education for operators, managers, and policymakers, often in partnership with the Water Environment Federation, American Water Works Association, and academic training programs at institutions like California Polytechnic State University, San Luis Obispo. Training topics include wastewater operations, biosolids handling, regulatory compliance, and emergency preparedness, and credentials are coordinated with certification bodies such as state operator certification programs administered by the California State Water Resources Control Board. The association also engages in public outreach and school-related programs to promote hygiene and water reuse awareness in communities across regions like the San Joaquin Valley and the San Francisco Bay Area.

Awards and Recognitions

CASA administers awards recognizing innovation, operational excellence, sustainability, and leadership among member agencies, comparable to honors from the Water Environment Federation and national clean water awards from the National Association of Clean Water Agencies. Recipients have included utilities such as the Orange County Sanitation District and notable projects involving recycled water programs tied to municipal partners like the City of San Diego and infrastructure initiatives in counties like Los Angeles County and Santa Clara County. Awards also highlight partnerships with engineering firms, research institutions, and community stakeholders including regional conservation groups and public health entities such as the California Department of Public Health.
